Well the blower is now asssembled finally. A terrible job. Almost everything had to be put together and it took two people and an impact wrench to complete. As we are 75 and 80 years old this was not easy. We are experienced but wow what a complicated job. The best thing I found was the parts chart that showed the bolt size. You really need power tools and an assortment of sockets of several different sizes. If you are not experienced don't this.
